I'm trying to install a Dell 1250C printer. However, I keep getting an erro message "Unknown USB Device (Device Descriptor Request Failed)" in the Devices and Printers window. I uninstalled the drivers and downloade the windows 8 drivers and tried to install. However, the installation process hangs up part way through and I have to use the task manager to stop it and reboot.

I do not see the USB port on the Thinkpad Yoga 12 when I install the printer drivers for this device. Was the USB port option removed from the list of available ports on the Yoga 12?
